superduper2009:
for q 6... when the ball is dropped... the displacement increases... when it bounces it comes nearer to the point where u left it... displacement decreases...then increases then decreases and so on and so forth...
the other properties do not change in this way... therfore answer is B

fr 1 9... just add up the momentum before collision...... 2mu - mu = mu
in the answers ... only A and B have a total momentum of mu...
but in D the spheres stick together...therfore it is inelastic collision...
The answer is A...
